Gas and acetylene torch lighter

ABSTRACT

A torch lighter box has a pair of spaced switch contacts extending through one face thereof upon which the nozzle of a torch may be placed; also has a pair of spaced ignition contacts extending through the same face aligned with the nozzle, and adapted to form a spark gap for igniting the gas issuing from the nozzle. A battery and a high voltage induction coil are housed within the box. A normally &#39;&#39;&#39;&#39;open&#39;&#39;&#39;&#39; electric circuit within the box connects the pairs of contacts, the battery and the coil, whereby whenever the nozzle is placed across the grounding contacts with gas issuing therefrom a spark will be induced across the ignition contacts to ignite the gas, the nozzle serving as a closing switch for the circuit.

Another object of the invention is to provide a gas and acetylene torch lighter of the above type comprising a metallic box, of small dimensions, which has on one face thereof a pair of spaced closing contacts across which the metallic nozzle of the torch may be placed; said closing contacts being insulated from the box itself. Said box also has on the same face thereof, but spaced from the closing contacts, a pair of spaced ignition contacts, also insulated from the box, adapted to form a spark gap for igniting the gas issuing from the nozzle of the torch; said ignition contacts being preferably aligned with the axis of the nozzle when the latter is in closing position.

The box also contains therein a battery, and a high voltage induction coil, and wiring connections between thepairs of contacts, battery, and induction coil to accomplish the desired result, that is, of igniting the gas issuing from the torch nozzle whenever the nozzle is placed across the closing contacts and when gas is issuing from the nozzle, the nozzle, per se, thus serving as a switch for closing the circuit between the pairs of contacts, the battery, and the induction coil.

I will explain the invention with respectto the accompanying drawings, which form a part of this application, in order that others familiar with the art may adopt and use the same; and will summarize in the claims, the novel features of construction, and novel combinations of parts, for which protection is desired.

IN SAID DRAWINGS FIG. 1 is a perspective view of my novel gas and acetylene torch lighter showing the pairs of spaced contacts, and showing the nozzle of a torch coupling the closing contacts of the box, and setting up a spark across the ignition contacts, and thus igniting the gas issuing from the nozzle.

FIG. 2 is a perspective view of the box, with cover removed, showing the arrangement of the pairs of contacts, the battery, the high voltage induction coil within the box, and showing the wiring circuit connections between the said parts.

As shown in the drawings, my novel gas and acetylene torch lighter comprises a box 1 of small dimensions, preferably rectangular, and preferably formed of metal although same may be formed on any other desired material. 1

Extending through relatively large bores in one face la of the box are a pair of metallic closing contacts 2, 3, which are insulated from the metal of the box, said contacts being spaced apart and disposed horizontally as shown in the drawings, upon which contacts 2, 3, the metallic nozzle N of a gas or acetylene torch T may be placed, the nozzle N acting as a switch to close the electric circuit contained in the box 1, herein after explained. The inner end of each contact rod 2, 3, is threaded to receive an outside nut 4 in contact with a washer 5 of insulating material which contacts the outer face of box Ia; also a washer 6 of insulating material, similar to washer 5, which engages the inner face of box la and is backed up by a locking nut 7, as shown.

Also extending through relatively large bores in the same face la of the box are a pair of spaced ignition rod contacts 8, 9, which are preferably vertically disposed and in alignment with and spaced from the tip of the nozzle N, so as to ignite the gases issuing from the nozzle N when a spark is induced across the contacts 8, 9, as shown in FIG. 1. The ignition contacts 8, 9, are insulated from the metal of face la of the box in the same manner as above described with respect to closing contacts 2, 3.

Within the box 1 is a battery 10, preferably a 6-volt dry cell battery, the positive terminal of which is connected by wire 11 (FIG. 2) to the closing contact 3, while the negative terminal is connected by wire 12 to the ignition contact 9. Also, within box I is a high voltage induction coil 13 (FIG. 2), one terminal of which is connected by wire 14 to the same ignition contact 9 4 as the wire 12 of the negative terminal of battery 10. Another terminal of coil 13 is connected by wire 15 to the closing contact 2, as shown in FIG. 2; while the third terminal of coil 13 is connected by wire 16 to ignition contact 8 of the box I, to complete the normally open wiring circuit of the box 1.

Thus, when the metallic nozzle N is placed across the closing contacts 2, 3, as shown in FIG. 1, the wiring circuit of the box 1 will be closed, inducing a spark S across the ignition contacts 8, 9, as shown in FIG. 1, and thereby igniting the gas issuing from the nozzle N, as shown, whereupon the nozzle may be removed from contacts 2, 3, and the lighted torch T used for any desired purpose, separated from the box 1. Upon such removal the circuit within box 1 will assume its normal open condition, the nozzle N serving as a switch to close the circuit, as above described.
